← ScienceWhich mechanism limits the energy coupled between transformer windings?
A)Leakage flux reduces mutual inductance✓
B)Eddy currents dissipate energy thermally
C)Hysteresis causes magnetic domain alignment lag
D)Capacitive coupling increases circuit impedance
💡 Explanation
Leakage flux bypasses the secondary winding, reducing the effective mutual inductance, because only the flux linking both windings transfers power. Therefore, less energy couples, rather than all flux coupling ideally.
